Tried the other location since we were in that part of town and had 3 hours to kill. There were couple-3 tables available when we got there (mid-afternoon), and by the time we left it fluctuated from couple to none throughout. So, constantly busy. The Americano was fabulous - and I mean really tasty - and still love that they have AC outlets EVERYWHERE. Even the couple picnic tables outside had outlets attached to them!
The only complaint I have are the seats. They are not comfortable. In some ways I think this is brilliant, so that people don't sit (like we did) for hours-on-end after a $7 order. We sat for about 2.5 hours, and came away with back aches and sore butts. That's what we get for squatting though, so not taking any stars away for that. Sambalatte will remain our go-to coffee spot.
